You can use the CTA button of Vidwidget service not only to follow links but also to run your own JavaScript logic, for example to open a modal window. To do so, when setting up the widget in your personal account, leave the “Link” field empty.
To intercept a Widget CTA button click, use the document.addEventListener (‘vw-btn-click’, CALLBACK); method, where CALLBACK is your own function.
An example of use, the result of which you can see on the current page:
<script>
function vw_callback(){
alert('My action');
}
document.addEventListener('vw-btn-click', vw_callback);
</script>
